N-Clear M Fleece Roller Filter - Nature Dimensions

The N-Clear Automatic Roller Filter replaces traditional filter socks with a fully automated mechanical filtration system that keeps your water clean without the constant swapping and cleaning. Using high-density fleece, it automatically advances when clogged—removing waste before it breaks down and keeping your system running efficiently.

Designed with a patent-pending fit, the N-Clear drops into most standard 4” filter sock holders with no modifications required. With optional adapters, it also works with larger openings and many AIO systems, making it one of the most versatile roller filters available.

Flow is strong and consistent, rated up to 800 GPH in single mode or 1600 GPH in dual mode. For larger systems or dual sock setups, you can link two units together and run them off a single controller for synchronized operation.

Setup is simple. The unit comes pre-assembled and ready to go—just connect and run. Fleece changes are just as easy with the EasyThread system, making replacements quick and clean without the usual hassle.

Smart control options include sensor-based operation that reacts to real water levels, along with an optional timer mode for scheduled advancement. Built for both freshwater and saltwater systems, it’s a reliable upgrade for anyone looking to simplify filtration and improve water clarity.
